using System;
using System.Drawing;
using System.Windows.Forms;

public class LeftScrollPanel : Panel
{
    private VScrollBar vScrollBar;

    public LeftScrollPanel()
    {
        this.AutoScroll = false; // 禁用默认滚动条
        this.DoubleBuffered = true; // 启用双缓冲减少闪烁

        vScrollBar = new VScrollBar();
        vScrollBar.Dock = DockStyle.Left; // 将滚动条放置在左侧
        vScrollBar.Minimum = 0;
        vScrollBar.Maximum = 100; // 根据需要调整最大值
        vScrollBar.ValueChanged += VScrollBar_ValueChanged;
        this.Controls.Add(vScrollBar);
    }

    private void VScrollBar_ValueChanged(object sender, EventArgs e)
    {
        this.AutoScrollPosition = new Point(0, -vScrollBar.Value);
    }

    protected override void OnScroll(ScrollEventArgs se)
    {
        base.OnScroll(se);
        vScrollBar.Value = -this.AutoScrollPosition.Y;
    }
}
